Removing specific items from a list

Hi all,
i have the following problem:
I have a list component on stage.
I have 10 Items in the list , selected index is 5.
Now i want to delete all the items above 5 (6-10).
I think an array would be a solution but im not so kind with
this so i need your help.
Thank you
Simon

if the instance name of your list is myList, then the
following code will remove all items after the currently selected
item:

Removing specific element from a list

Hello, I'm very new to java, and to programming in general.
I'm trying to write a secret santa app for my family for christmas. Essentially the idea is that 7 names are put into a list, and each time a name is "pulled" (i.e. randomly assigned to a name /= itself) it will be removed from the list of available names to assign.
String[] nList = { name2, name3, name4, name5, name6, name7 }; // store names for random use
Random r = new Random();
name1assign = nList[r.nextInt(nList.length)];
String[] nList2 = { name1, name3, name4, name5, name6, name7 };
name2assign = nList2[r.nextInt(nList2.length)];
My goal for this is to take the string that is equal to name1assign, and remove an element with that string from nList2.
Can anyone give me some advice in this matter?
Thanks.

Sometimes a null value is used to indicate an 'empty' array element, but it would be better to try collections instead.
You could use an ArrayList instead of an array. This has methods to remove items by index or value.
An ArrayList also works with Collections.shuffle, which allows you to simply iterate over the list and not deal with random or removing elements at all.

How: can i get a specificated item from a list with more than 100.000 items

Hi,
i have a very large list and i got always an exception that the list has more than 5000 items and cant query!! But in the default list view i can see, order and filter all items. So how can i do this by c#?

Hi,
According to your description, my understanding is that you want to get a specific list item form a list which with more than 100000 items using C#.
I suggest you can use CAML Query with some condition and set Row Limit to specify the number of items to return.
Here is a detailed code demo for your reference:

HT204088 I want to remove specific items from my purchase history. for example items that were free, for trial were not purchased.

Hi, This must be quite a common problem. A purchase is defined as something one acquires by paying.
The app store gives you access to download free items or download items for trial. Most are rubbish.
Because the ipad doesn't support multiple login accounts everyone uses one apple account to download the apps.
Over the months i have tens of apps that have been downloaded and deleted. they still appear in my account as 'purchases'.
How do i delete items that have been deleted and not been paid for?
Thank you.

I don't think you can, Peter.
Apple regard a download from the App Store as a purchase. You can hide it and ignore it, but not cancel it.
I am not so sure about the system if you're talking about apps previously downloaded 'privately' that are later subject to Apple updates.

Removing specific items from the "Open With" menu

I use VMWare Fusion and have an issue with the "Open With" context menu for documents that I can open with VMWare. Several images that have been deleted continue to show up in the context menu. How can I remove them?
I tried renaming the com.launcher.plist solution described in the "how to" section, but to no avail...

When you say you "tried renaming the com.launcher.plist", did you do what is described [here|http://support.apple.com/kb/TA24770?viewlocale=en_US] or something else?
Also have a look at [this thread|http://discussions.apple.com/thread.jspa?threadID=1486735].

How do I removing a specific item from an Array?

Hi there.
I am having an array of movieclips and when my circle(controlled with the keyboard) hitTests true with one of the movieclips inside that array i want to remove that movieclip from the array so when i hitTest it again it returns false (I hitTest using a "for in" with that array).
How do i remove a specific item from within an array?
Can someone help me? Thanks a lot.

i haven't noticed anyone showing deference because of the points. in fact, i've seen some people (a minority, to be sure) be just obnoxious about it. i never encountered that before: some people feel they have power because they can dole out points.
but overall i agree with you: the loss of the list of threads i am participating in, along with the most recent posters name, is a significant drawback of the new forums. and there's nothing new in these forums that offsets that drawback.
in addition, i think we've lost way more than 1/2 the older threads. that's a lot of information that's no longer available.

Hi Vijay,
(a) every request on SDN is expected as urgent... If you won't use this word in the future, you'll have more time for solving your problems
(b) If your listbox.getModel() returns the DefaultListModel, you can call removeItem(String key) on the model; see http://media.sdn.sap.com/javadocs/preNW04/SP2/60_sp2_javadocs/htmlb/com/sapportals/htmlb/DefaultListModel.html#removeItem(java.lang.String) for details
Hope it helps

How to remove these items from Infopath ribbon in web enable form?

Hi All,
I am using custom list form customized in infopath 2013, I want to remove these items from ribbon :
I tried with Infopath "form Options" like:
But still showing "Picture-1" options. How to remove those items from ribbob?

Hi,
I understand that in the list view web part, you wanted to remove the ribbon of InfoPath form.
There are to mothed to achieve it:
Open the list, click new item, edit page, edit web part, unclick the ‘Show InfoPath Ribbon or toolbar’ box, the new item page will remove the riibon. Then when you open the page which has the list view web part, the ribbon of InfoPath form will also
be removed.
Open the page which has the list view web part, edit page, edit the list view web part, unclick the ‘Show InfoPath Ribbon or toolbar’ box, the ribbon of InfoPath form in the web part will be removed. Then when you open the list, the ribbon of InfoPath form
will also be removed.
The two method edit the same page newifs.aspx, so the list and the webpart will be modified in the same time.
Thank you for your understanding.

Hi Jurgen,
when i check the material document and accounting document,it was showing that said amount in negative sign and transaction done by MI10 means posted differences with out reference to document.
it means the user may entered wrongly i think.
was there any GRIR account for MI10?
MI10 does not have reversal or cancel?
so how to resolve it?
as per my idea it can be done by FI posting.
please help to resolve.
Thanks in advance.

Is there a way to remove an app from the list of previously installed apps?

Is there a way to remove an app from the list of previously installed app?
The list that comes up when you click on the Purchased icon when updating apps.
The list is becoming quite large after I installed and tried out a few apps.

nvm. I found it.

I would like to know, on the ringtone page, where you can select songs out of your music library, is there a way to remove a song from the list after its selected? I would thin there would be a way to "delete" the songs from the list. (Clock app)

I would like to know, on the ringtone page, where you can select songs out of your music library, is there a way to remove a song from the list after its selected? I would thin there would be a way to "delete" the songs from the list. (Clock app)
Let me explain:
In the clock app for ios 6.0.2 I am a little confused. It allows you to go into your music library, and create a ringtone using any songs you choose. However, I cannot find a way to remove a song from this list, just like I cannot delete one of the preset ringtones (which I'm not trying to do, but just as an example)
Thanks for your time! If you need more information just ask.
(I believe both my iPod and iTunes are up to date)

I believe you just are able to delete them from iTunes.
Hope it will be helpful
